There are a variety of grips that pitchers use to throw two-seam fastballs, but the most common occurs when the pitcher puts his two fingers directly on top of the part of the ball where the seams are closest together. If thrown with the same finger pressure, two-seam and four-seam fa...

Layout design - yield pillars - longwall - two-seam mining - stability analysisResults of instrumentation, test mining and computer aided stability analyses were combined to design the most stable gate road layout for two-seam longwall mining at the Plateau Mining Company. Five layouts were ...
“I've been working on that two-seam runner,” Eovaldi said. “It wasn't as great today. In the offseason, the TrackMan results were awesome. We had good results from it and I was throwing it like I wanted to. Today, I was, I think, a little quick with everything. That’s a...
Introduced in solid copper, the light SEAM TWO is a unique and refined piece. The combination of its precious material and artistry in the complex production, distinguishes the light as an exclusive object.
With its inherent sculptural quality and accurate folds the light SEAM TWO is an identifying icon for e15. Applying simple but elaborated construction methods and balanced proportions, SEAM TWO follows Mark Holmes' principle of reduced components and foc
The use of yield pillars minimizes the stresses transmitted from the upper to the lower seam. However, yielding must not impact the good, long-term stability needed to prevent subsidence for a large portion of the mine beneath the Green River channel. In 1990, long-term stability was ...
In this study, a new method for predicting subsidence in two-seam mining is proposed. First, the surface subsidence due to mining the upper seam is monitored. Then, taking the subsidence data as indicators, the optimal mechanical parameters of overlying strata can be obtained by orthogonal ...
